GO-CART OR CHILDS CHAIR.

SPECIFICATION forming part of Letters Patent No. 749,119, dated January 5, 1904.

Application filed October 2, 1903. Serial No. 175,467. (No model.)

To all whom it may concern: brace-bar is of rectangular cross-section and Be it known that I, JOHN WEBER, Jr., a citiis pivotally secured to the movable member zen of the United States of America, residing by the eared plate a, free to adjust itself to at Toledo, in the countyof Lucas and State any angle in the vertical central plane of the 5 5 of Ohio, have invented certain new and useseat. The friction-lock F consists of an inful Improvements in Go-Carls or Ohildrens closing casing b, formed of a single piece of Chairs, of which the following is a specificasheet metal, with earsc for attaching it to the tion, reference being had therein to the acsupporting-frame and with openings e e, companying drawings. through which the. brace-bar is adapted to 60 to This invention relates more particularly to freely slide, one of said openings forming a an improvement in means forvarying the poguide-bearing for the bar. Housed within sition of the back and footboard of a go-cart the casing is a friction-dog f, formed of a or childs chair relatively to the seat thereof; short metal cylinder attached to a pull-rod g, and it consists in the peculiar construction, guided through a hole in the casing and hav- 65 t5 arrangement, and operation of a seat having ing a spring h pressing upon it. The side 61 the back and footboard shiftably connected of the casing is inclined, as shown, whereby thereto and means for independently holding the dog f under the action of the spring is each in its adjusted position relatively to the pressed into frictional engagement with the seat, all as more fully hereinafter described, brace-bar, and thereby makes a self-locking 7o and shown in the accompanying drawings, in fastening.

which Referring more particularly to the adjust- Fignre 1 is a detached side elevation eming-fixture for the back, as shown in the drawbodying my invention of the back, seat, and ings, the push-rod g is extended upwardly footboard of a go-cart or childs chair. Fig. through a guide-bearing i and terminates in 75 2 is a horizontal section on line at a, Fig l. a handholdj. The casing b of this fixture is Fig.3is an enlarged front elevation ofa porsecured to a transverse bar H, supported tion of Fig. 1. Fig. 4 is av bottom plan view upon brackets I, which project rearwardly of the lower portion of Fig. 3. Fig. 5 is a defrom the seat and to which the cross-bar H tached rear elevation of the friction-lock. is pivotally secured at k, thereby permitting 8o Fig. 6 is a perspective view of the housing of the brace-bar to change its angularity in adthe friction-lock. j usting the back to any desired incline.

A represents the seat fixedly mounted upon In the fixture shown for adjusting the footthe supporting-frame ('not shown) of a go-cart board the friction-lock is secured to a fixed or childs chair, and B and 0 represent the transverse bar K, which is part of a depend- 85 movable members-that is, theback and footing bracket L, secured to the under side of boardeach being secured to the seat by suitthe seat in position to receive the brace-bar, able hinges D, so that the positions thereof which is shown curved, and it will be underrelative to the seat may be changed. My in- -stood that the curving of this bar is merely vention has particular reference to the means an equivalent for the pivotal cross-bar H of 0 40 for holding the back and the footboard in the other fixture. The actuating means for their adjusted position each independently of the dog in the footboard-fixture consists of a the other. These means consist of two fixcranked rod M, transversely secured in beartures, one for the back and the other for the ings below the seat and extending to one side footboard, each operating independently of thereof, a hand-wheel N being secured to the 95 the other. In the drawings I have shown the outer end and its cranked end being confixtures of slightly-different construction;but nected by a short pull-rod g with the dog, all

itis to be understood thateither maybe adapt as shown in Figs. 3 and 4. ed to take the place of the other. Each of The operation of my self-locking fixture these fixtures embodies a brace-bar E, pivotwill be readily understood from the descrip- 100 ally secured to the movable member, and a tion. Its construction is simple, strong, and friction-lock F, carried by the seat. The easilyoperatedwhether the seat is empty or occupied. It is entirely out of the way of the supporting-frame and as safe as a positive lock.

Having thus fully described my invention, what I claim is 1. In a go-cart or childs chair having the back or footboard shiftably connected to the seat, a self-locking fixture for holding said back or footboard ad justably in position and comprising a brace-bar pivotally secured to said back or footboard, a friction-lock composed of a casing supported by the seat in position to guide the brace-bar through openings in the walls of the casing and forming a wedge-shaped space between one side of said brace-bar and the opposite wall of the casing, a cylindrically-shaped dog inclosed in said space, means for manually operating the dog and a spring for actuating said dog normally into its locked position with the brace-bar, provision being made whereby the brace-rod is adapted to move freely through the openings in the casing in the adjustment of the back or footboard when said frictiondog is moved out of engagement therewith.

2. In a go-cart or childs chair having the back or footboard shiftably connected to the seat, a self-locking fixture for holding said back or footboard adjustably in position and comprising a rectangular brace-bar pivotally secured to said back or footboard in the central vertical plane of the seat a friction-lock composed of a casing supported by the seat in position to guide said brace-bar through openings in the walls of the casing and forming a wedge-shaped space between one side of said brace-bar and the opposite wall of the casing, a cylindrically-shaped dog inclosed in said space, a spring for normally holding said dog in its locked position with the bracebar and a pull-rod connected to the dog and adapted to withdraw the same from its locked position, provision being made for the bracerod to slide freely through the casing for adjusting the back or footboard to any desired position in. relation to said seat when the dog is withdrawn from engagement therewith.

3. In a go-cart or childs chair, the combination with the seat of a back and footboard hinged thereto, brace-bars pivotally secured to said back and footboard in the Vertical central plane of the seat, and a friction-lock for each brace-bar comprising a casing supported from the seat in position to guide the brace-bar through openings in the walls of the casing, provision being made to permit the brace-bar to slide freely through said casing in adjusting said back or footboard from a vertical position or nearly so to a horizontal position or nearly so, a cylindrically-shaped friction dog inclosed in a wedge shaped pocket in the casing formed by one side of the brace-bar and the opposite wall of the casing, which is inclined thereto, a spring bearing against the friction-dog to hold the same normally in its locking positions and means for manually operating the dog.

4. In a g0-cart or childs chair, the combination with the seat and footboard hinged thereto, of a self-locking fixture for holding said footboard adj ustably in position thereto and comprising a brace-bar pivotally secured to the footboard in the vertical central plane of the seat, a friction-lock composed of a casing formed with openings in the opposite walls thereof for the passageot' the brace-bar through the casing, a bracket secured to the under side of the seat supporting said casing in position for the brace-bar to engage the openings ofthecasing,thebrace-barbeingcurvedtoslide freely through said openings, a cylindricallyshaped friction-dog located in a wedge-shaped space in the casing formed between one side of the brace-bar and the opposite Wall of the casing, which is inclined thereto, a spring for normally actuating the dog into its locked position with the brace-bar, a pull-rod adapted to withdraw said dog from said locked position and an actuating crank-shaft journaled transversely below the seat and extending to one side thereof, said crank-shaft carrying an operating hand-wheel at its outer end and having the pull-rod attached to the end of its crank.

In testimony whereof I afiix my signature in presence of two witnesses.
